Comparison of Intraocular Tamponade in Patients with Peripheral Tear-Induced Retinal Detachment and Coexisting Macular Hole without High Myopia

Abstract

Abstract Introduction To introduce the surgical results and examine the effect of intraocular tamponades on surgical outcomes in patients with coexisting macular hole (MH) and rhegmatogenous retinal detachment (RRD) without high myopia. Methods This retrospective, cross-sectional, two-center study was carried out with 29 eyes of 29 patients. The patients were divided into two groups according to the intraocular tamponade used in surgery: silicone oil (Group 1) and C3F8 gas (Group 2). In all patients, the internal limiting membrane was peeled during surgery. Exclusion criteria were determined as RRD with MH due to high myopia (≥ 6 D) without peripheral retinal tears and traumatic MH. Results In Group 1, the median preoperative best-corrected visual acuity (BCVA) was 3.0 (M ± SD: 2.85 ± 0.27) logMAR, while the median postoperative BCVA was 1.0 (M ± SD: 1.39 ± 0.83) logMAR (p < 0.001). In Group 2, the median preoperative BCVA was 3.0 (M ± SD: 2.37 ± 0.93) logMAR, while the median postoperative BCVA was 0.76 (M ± SD: 1.06 ± 0.86) logMAR (p = 0.008). The retinal attachment success rate was 15/17 (89.3%) in Group 1, and 11/12 (91.7%) in Group 2 (p = 0.64). The MH closure rate was 12/17 (71.6%) in Group 1, and 10/12 (78.1%) in Group 2 (p = 0.52). No difference was determined between the groups in terms of preoperative and postoperative BCVA, preoperative and postoperative intraocular pressure, and BCVA improvement. Conclusions The study results showed no significant difference between using silicone oil or C3F8 gas as an intraocular tamponade after internal limiting membrane peeling in patients with RRD due to peripheral tear with coexisting MH.
